The bucking started within a couple of years and was so intermittent -- cold weather, hot weather, city driving, turnpike driving, then clearing up for a day, a week or months.

Very exasperating.

Finally, a couple of years ago, it continued long enough for a mechanic to observe and find that one of two microswitches on the throttle control was the culprit. His fix was a bit of lubricant and nary a buck since.

Hope this tale helps the Jetta owner in Simsbury.

A: Obviously you found one of those mechanics who is worth his weight in gold. And I'm glad that you passed on your tale of eventually curing a bucking Golf.
